o Allow this to work with "nodevice random" by fixing where the MALLOC pool is defined.
o Fix the explicit reseed code. This was correct as submitted, but in the project branch doesn't need to set the "seeded" bit as this is done correctly in the "unblock" function.
o Remove some debug ifdeffing.
o Adjust comments.

"assignment makes pointer from integer without a cast", by changing the
cmd_lst and rbis members of struct ahci_port from integers to pointers.
Also surround a pow-of-2 test expression with parentheses to clarify it,
and avoid another gcc warning.

I replaced the sx_* locks that Arthur used with regular mutexes; this turned out the be the wrong thing to do as the locks need to be sleepable. Revert this folly.

extensions, we can change the .byte directives in sys/dev/random/ivy.c
to plain 'rdrand' mnemonics. This already worked for clang users, but
now it will also work for gcc users.

Prior to this change if the "-g" option was not specified then a listening
socket for tunneling gdb packets would be opened at port 6466. If a second
virtual machine is fired up, also without the "-g" option, then that would
fail because there is already a listener on port 6466.
After this change if a gdb tunnel port needs to be created it needs to be
explicitly specified with a "-g <portnum>" command line option.

This prevents repeated notifications of the same event.
Status of these events may be viewed at any time by viewing the
SMART/Health Info Page using nvmecontrol, whether or not asynchronous
events notifications for those events are enabled. This log page can
be viewed using:
nvmecontrol logpage -p 2 <ctrlr id>
Future enhancements may re-enable these notifications on a periodic basis
so that if the notified condition persists, it will continue to be logged.

approach can cause a panic if the device is closed which the taskqueue
thread is active, or if a kernel module containing a provider is unloaded
while retained enablings are present and the dtrace device isn't opened.

The AR5212 series of MACs implement the same channel counters as the
later 11n chips - except, of course, the 11n specific counter (extension
channel busy.)
This allows users of these NICs to use 'athsurvey' to see how busy their
current channel is.
Tested:
* AR5212, AR2413 NICs, STA mode

Add a SYSINIT that forces a reseed during proc0 setup, which happens
fairly late in the boot process.
Add a RANDOM_DEBUG option which enables some debugging printf()s.
Add a new RANDOM_ATTACH entropy source which harvests entropy from the
get_cyclecount() delta across each call to a device attach method.
This means we can't count on /var being present, so something will need to be done about harvesting /var/db/entropy/... .
Some policy now needs to be sorted out, and a pre-sync cache needs to be written, but apart from that we are now ready to go.
Over to review.
Since so many programs don't check return value, always NUL terminate
the buf...
fix rounding when using base 1024 (the bug that started it all)...
add a set of test cases so we can make sure that things don't break
in the future...
Thanks to Clifton Royston for testing and the test program...

the kernel, or when a new kernel has been installed but the system has
